Would anyone happen to have a copy of the system diagram for the heated front seats in the 2500 trucks? In my 2015, the passengers seat works just fine, but the drivers seat heat is acting wonky. Sometimes it works fine, others the light on the dash stays lit but no heat, others it will heat one cycle and not run another cycle no matter how long you wait unless I turn the truck off and on again. I'm thinking I've got a sticky relay somewhere but not sure where to start without knowing where the modules are.
